Developer Abelardo Gonzalez has created an open-source font designed to help people with dyslexia read more easily. Dubbed OpenDyslexic, the font is currently available as a free download, in the form of a Safari and Chrome extension, a bookmarklet, and a free iOS web-browsing app. OpenDyslexic has also been incorporated into several third-party apps, including popular read-it-later service Instapaper.
Each OpenDyslexic letter features a heavy-weighted bottom, intended to lend "gravity" to text displayed with the font. Presenting a character in this way is believed to help prevent the letters from rotating, flipping, or becoming otherwise confused in the brains of some dyslexics.
